Create Jar File from Package on Command Line

In Java programming, creating a JAR (Java Archive) file from a package on the command line is a useful skill. This process allows you to package multiple Java class files, resources, and metadata into a single archive file for easy distribution and execution.

To create a JAR file from a package on the command line, follow these steps:

1. Compile your Java source files into .class files:

javac your_package/*.java

2. Create a manifest file:

echo Main-Class: your_package.MainClass > manifest.txt

3. Create the JAR file:

jar cvfm myjar.jar manifest.txt your_package/*.class

By following these steps, you can create a JAR file that includes your Java package for distribution or execution on other systems seamlessly.

“Packages and JAR files are essential components in Java development, streamlining the process of managing and sharing your codebase.”

Experiment with creating JAR files from different packages to enhance your understanding of this fundamental Java concept.
